Installation & Handling Notes
Proper installation is key to ensuring the performance and durability of refractory castables. At Dynamic Refractories Sdn. Bhd., we follow proven practices and provide technical support to help you achieve optimal results.
1. Surface Preparation
Before applying any castable material, ensure that all surfaces are clean, dry, and free from dust, oil, loose particles, or any other contaminants that could affect adhesion. All anchors and reinforcement systems should be securely installed and positioned according to the design specifications. Surface priming may be necessary depending on substrate conditions.
2. Mixing
Use clean, potable water for mixing, and ensure that the temperature of both the water and dry mix is within the recommended range. Use a high-shear mechanical mixer to achieve a homogeneous and lump-free consistency. Add water gradually while mixing, following the product-specific guidelines. Over-watering must be avoided, as it can compromise the mechanical strength and durability of the castable.
3. Application Method
Castables can be applied using different techniques such as casting, gunning, or ramming, based on the grade and application requirement. During casting, it is essential to use proper mechanical or manual vibration to eliminate trapped air and ensure dense compaction. For gunning applications, ensure a consistent feed and air pressure to avoid rebound and ensure uniform placement.
4. Curing
Once installation is complete, the material should be kept covered with plastic sheets or damp burlap and allowed to cure undisturbed at ambient temperature for a minimum of 24 hours. This curing period allows the castable to develop sufficient green strength and helps to prevent rapid surface drying, which can lead to shrinkage cracks.
5. Dry-Out
After curing, the castable must undergo a carefully controlled dry-out process to remove retained moisture. This involves gradually increasing the temperature in stages, as specified in the recommended heating schedule. Skipping this process or increasing the temperature too rapidly can cause steam spalling, compromising both safety and the integrity of the lining.
6. Storage
Castable refractory materials should be stored in a dry, cool, and well-ventilated area, away from direct contact with moisture or damp surfaces. Bags should remain sealed until use, and materials should be consumed within their specified shelf life to ensure optimal performance. Avoid stacking bags in a manner that may lead to damage or exposure to environmental elements.
7. Safety Precautions
Always wear appropriate personal protective equipment (PPE), including gloves, safety glasses, dust masks, and protective clothing, while handling and installing castables. Avoid direct contact with skin and eyes, and take precautions to prevent inhalation of dust during mixing and application. Refer to the product’s Safety Data Sheet (SDS) for comprehensive safety and first-aid instructions.
